1. Write down 12 different examples of functions found in the real world. Three examples must be expressed verbally, two numerically, four algebraically and three geometrically. Also, write their domains and ranges. 2. In the even numbered Problems 13-24, determine whether the graph is that of a function. If it is, use the graph to find: (a) The domain and range, (b) The intercepts, if any, (c) whether the function is even, odd, or 13. neither., (d) Any symmetry with respect to the x-axis, the y-axis or the origin. 14. ** -3 15. -T 16. 18. 19. 20.
